Thermoplastics valves — Torque — Test method
This document specifies a test method for the determination of the opening, closing and running torque of thermoplastics valves. This document is applicable to all types of manually operable thermoplastics valves, with or without actuator, intended to be used for the transport of fluids. NOTE 1 Examples of valve types tested with this method are in ISO 4437-4, ISO 16135, ISO 16136, ISO 16138, ISO 16139, ISO 16486-4, ISO 21787, EN 1555-4[13] and EN 12201-4 [14]. This document does not specify the relationship between the torque and its possible increase after prolonged use of the valve under a specific working condition or wear/chemical aggression of the materials. NOTE 2 Concerning the chemical aggression of the materials, a collection of data is reported in ISO/TR 10358 concerning the endurance test necessary to confirm the ability of hand-operated plastics valves to withstand prolonged use with repeated opening and closing operations. Further information is provided in ISO 8659.
Robinets en matériaux thermoplastiques — Couple de manoeuvre — Méthode d'essai
Le présent document spécifie une méthode d’essai pour la détermination du couple d’ouverture, de fermeture et de fonctionnement des robinets en matériaux thermoplastiques. Le présent document s’applique à tous les types de robinets en matériaux thermoplastiques manœuvrables manuellement, avec ou sans actionneur, destinés à être utilisés pour le transport des fluides. NOTE 1 Des exemples de types d'appareils de robinetterie soumis à essai avec la présente méthode sont dans l'ISO 4437-4, l'ISO 16135, l'ISO 16136, l'ISO 16138, l'ISO 16139, l'ISO 16486-4, l'ISO 21787, l'EN 1555-4[13] et l'EN 12201-4[14]. Le présent document ne spécifie pas la relation entre le couple de manœuvre et son augmentation possible après une utilisation prolongée de l’appareil de robinetterie dans des conditions de fonctionnement spécifiques ou après une usure/agression chimique des matériaux. NOTE 2 Concernant l’agression chimique des matériaux, un ensemble de données est disponible dans l’ISO/TR 10358 concernant l’essai d’endurance nécessaire pour confirmer l’aptitude des robinets en matériaux thermoplastiques manœuvrés à la main à supporter une utilisation prolongée, avec des manœuvres d’ouverture et de fermeture répétées. Des informations complémentaires sont données dans l’ISO 8659.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates

L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux
de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
